NEW QUESTION # 26
What are the roles of 802.1X authenticators and authentication servers?
- A. The authenticator supports only EAP, while the authentication server supports only RADIUS.
- B. The authenticator is a RADIUS client and the authentication server is a RADIUS server.
- C. The authenticator makes access decisions and the server communicates them to the supplicant.
- D. The authenticator stores the user account database, while the server stores access policies.
Answer: B
Explanation:
In the 802.1X network access control model, the roles of the authenticator and the authentication server are distinct yet complementary. The authenticator acts as a RADIUS client, which is a network device, like a switch or wireless access point, that directly interfaces with the client machine (supplicant). The authentication server, typically a RADIUS server, is responsible for verifying the credentials provided by the supplicant through the authenticator. This setup helps in separating the duties where the authenticator enforces authentication but does not decide on the validity of the credentials, which is the role of the authentication server.References:

NEW QUESTION # 27
What are some functions of an AruDaOS user role?
- A. The role determines which wireless networks (SSiDs) a user is permitted to access
- B. The role determines which firewall policies and bandwidth contract apply to the clients traffic
- C. The role determines which control plane ACL rules apply to the client's traffic
- D. The role determines which authentication methods the user must pass to gain network access
Answer: D
NEW QUESTION # 28 
What is another setting that you must configure on the switch to meet these requirements?
- A. Set the aaa authentication login method for SSH to the "radius" server-group (with local as backup).
- B. Disable SSH on the default VRF and enable it on the mgmt VRF instead.
- C. Configure a CPPM username and password that match a CPPM admin account.
- D. Create port-access roles with the same names of the roles that CPPM will send in Aruba-Admin-Role VSAs.
Answer: A
Explanation:
To meet the requirements for configuring an ArubaOS-CX switch for integration with ClearPass Policy Manager (CPPM), it is necessary to set the AAA authentication login method for SSH to use the "radius" server-group, with "local" as a backup. This ensures that when an admin attempts to SSH into the switch, the authentication request is first sent to CPPM via RADIUS. If CPPM is unavailable, the switch will fall back to using local authentication12.
Here's why the other options are not correct:
Option B is incorrect because configuring a CPPM username and password on the switch that matches a CPPM admin account is not required for SSH login; rather, the switch needs to be configured to communicate with CPPM for authentication.
Option C is incorrect because while CPPM will send Aruba-Admin-Role Vendor-Specific Attributes (VSAs), the switch does not need to have port-access roles created with the same names; it needs to interpret the VSA to assign the correct role.
Option D is incorrect because disabling SSH on the default VRF and enabling it on the mgmt VRF is not related to the authentication process with CPPM.
Therefore, the correct answer is A, as setting the AAA authentication login method for SSH to the "radius" server-group with "local" as backup is a key step in ensuring that the switch can authenticate admins through CPPM while providing a fallback method12.
NEW QUESTION # 29
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?
- A. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses
802.1X authentication. - B. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.
- C. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
- D. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
Answer: C
Explanation:
WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
NEW QUESTION # 30
What is a guideline for managing local certificates on an ArubaOS-Switch?
- A. Install an Online Certificate Status Protocol (OCSP) certificate to simplify the process of enrolling and re-enrolling for certificate
- B. Before installing the local certificate, create a trust anchor (TA) profile with the root CA certificate for the certificate that you will install
- C. Create a self-signed certificate online on the switch because ArubaOS-Switches do not support CA-signed certificates.
- D. Generate the certificate signing request (CSR) with a program offline, then, install both the certificate and the private key on the switch in a single file.
Answer: D
NEW QUESTION # 31
A company has an ArubaOS solution. The company wants to prevent users assigned to the "user_group1" role from using gaming and peer-to-peer applications.
What is the recommended approach for these requirements?
- A. Create service aliases for the TCP ports associated with gaming and peer-to-per applications, and use those aliases in access control rules for the "user_group" rules.
- B. Create ALGs for the gaming and peer-to-peer applications, and deny the "user_group1" role on the ALGs.
- C. Add access control rules to the "user_group1" role, which deny HTTP/HTTPS traffic to IP addresses associated with gaming and peer-to-peer applications.
- D. Make sure DPI is enabled, and add application rules that deny gaming and peer-to-peer applications to the "user_groupr role.
Answer: D
Explanation:
The recommended approach for preventing users in the "user_group1" role from using gaming and peer-to-peer applications in an ArubaOS environment is to enable Deep Packet Inspection (DPI) and add application rules that specifically deny access to these types of applications for the role. DPI allows the network system to analyze the content of network traffic in real time and apply policies based on what it detects, including blocking specific applications like gaming and peer-to-peer sharing. This capability is essential for effectively managing application usage on the network and ensuring compliance with organizational policies. Application-specific rules provide precise control over the network traffic by identifying the application regardless of the network port used, making it a more effective method than blocking based on ports or IP addresses.
NEW QUESTION # 32

What is a use case for Transport Layer Security (TLS)?
- A. to establish a framework for devices to determine when to trust other devices' certificates
- B. to provide a secure alternative to certificate authentication that is easier to implement
- C. to enable a client and a server to establish secure communications for another protocol
- D. to enable two parties to asymmetrically encrypt and authenticate all data that passes be-tween them
Answer: C
Explanation:
The use case for Transport Layer Security (TLS) is to enable a client and a server to establish secure communications for another protocol. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used for web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, and voice-over-IP (VoIP). TLS operates between the transport layer and the application layer of the Internet Protocol Suite and is used to secure various other protocols like HTTP (resulting in HTTPS), SMTP, IMAP, and more. This protocol ensures privacy and data integrity between two communicating applications.
Detailed information about TLS and its use cases can be found in IETF RFC 5246, which outlines the specifications for TLS 1.2, and in subsequent RFCs that define TLS 1.3.
NEW QUESTION # 35
You have an Aruba Mobility Controller (MC) that is locked in a closet. What is another step that Aruba recommends to protect the MC from unauthorized access?
- A. Use local authentication rather than external authentication to authenticate admins.
- B. Disable local authentication of administrators entirely.
- C. Change the password recovery password.
- D. Set the local admin password to a long random value that is unknown or locked up securely.
Answer: C
Explanation:
Protecting an Aruba Mobility Controller from unauthorized access involves several layers of security. One recommendation is to change the password recovery password, which is a special type of password used to recover access to the device in the event the admin password is lost. Changing this to something complex and unique adds an additional layer of security in the event the physical security of the device is compromised.
NEW QUESTION # 36
What is one of the roles of the network access server (NAS) in the AAA framewonx?
- A. It negotiates with each user's device to determine which EAP method is used for authentication
- B. It determines which resources authenticated users are allowed to access and monitors each users session
- C. It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.
- D. It enforces access to network services and sends accounting information to the AAA server
Answer: D
Explanation:
In the AAA (Authentication, Authorization, and Accounting) framework, the role of the Network Access Server (NAS) is to act as a gateway that enforces access to network services and sends accounting information to the AAA server. The NAS initially requests authentication information from the user and then passes that information to the AAA server. It also enforces the access policies as provided by the AAA server after authentication and provides accounting data to the AAA server based on user activity.
References:
Technical literature on AAA protocols which often includes a description of the roles and responsibilities of a Network Access Server.

NEW QUESTION # 37
What is social engineering?
- A. Hackers spoof the source IP address in their communications so they appear to be a legitimate user.
- B. Hackers intercept traffic between two users, eavesdrop on their messages, and pretend to be one or both users.
- C. Hackers use employees to circumvent network security and gather the information they need to launch an attack.
- D. Hackers use Artificial Intelligence (Al) to mimic a user's online behavior so they can infiltrate a network and launch an attack.
Answer: C
Explanation:
Social engineering in the context of network security refers to the techniques used by hackers to manipulate individuals into breaking normal security procedures and best practices to gain unauthorized access to systems, networks, or physical locations, or for financial gain. Hackers use various forms of deception to trick employees into handing over confidential or personal information that can be used for fraudulent purposes. This definition encompasses phishing attacks, pretexting, baiting, and other manipulative techniques designed to exploit human psychology. Unlike other hacking methods that rely on technical means, social engineering targets the human element of security. References to social engineering, its methods, and defense strategies are commonly found in security training manuals, cybersecurity awareness programs, and authoritative resources like those from the SANS Institute or cybersecurity agencies.

- C. WPA3-Personai prevents eavesdropping on other users' wireless traffic by a user who knows the passphrase for the WLAN.
- D. WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password
Answer: D
NEW QUESTION # 39
How does the ArubaOS firewall determine which rules to apply to a specific client's traffic?
- A. The firewall applies every rule that includes the client's IP address as the source or destination.
- B. The firewall applies every rule that includes the dent's IP address as the source.
- C. The firewall applies thee rules in policies associated with the client's user role.
- D. The firewall applies the rules in policies associated with the client's wlan
Answer: C
Explanation:
The ArubaOS firewall determines which rules to apply to a specific client's traffic based on the rules in policies associated with the client's user role. User roles are a fundamental part of ArubaOS and the firewall policies they encompass. These roles contain policies that dictate permissions and restrictions for network traffic. When a client authenticates, it is assigned a role, and the firewall enforces the rules defined within that role for the client's traffic.

NEW QUESTION # 40
Your Aruba Mobility Master-based solution has detected a suspected rogue AP. Among other information, the ArubaOS Detected Radios page lists this information for the AP:
SSID = PublicWiFi
BSSID = a8:bd:27:12:34:56
Match method = Plus one
Match method = Eth-Wired-Mac-Table
The security team asks you to explain why this AP is classified as a rogue. What should you explain?
- A. The AP has been detected using multiple MAC addresses. This indicates that the AP is spoofing its MAC address, which qualifies it as a suspected rogue.
- B. The AP is probably connected to your LAN because it has a BSSID that is close to a MAC address that has been detected in your LAN. Because it does not belong to the company, it is a suspected rogue.
- C. The AP is an AP that belongs to your solution. However, the ArubaOS has detected that it is behaving suspiciously. It might have been compromised, so it is classified as a suspected rogue.
- D. The AP has a BSSID that is close to your authorized APs' BSSIDs. This indicates that the AP might be spoofing the corporate SSID and attempting to lure clients to it, making the AP a suspected rogue.
Answer: B
Explanation:
The Match method 'Eth-Wired-Mac-Table' suggests that the BSSID of the rogue AP has been found in the Ethernet (wired) MAC address table of the network infrastructure. This means the AP is physically connected to the LAN. If the BSSID does not match the company's authorized APs, it implies the AP is unauthorized and hence classified as a rogue.

NEW QUESTION # 49
Refer to the exhibit.
This Aruba Mobility Controller (MC) should authenticate managers who access the Web Ul to ClearPass Policy Manager (CPPM) ClearPass admins have asked you to use RADIUS and explained that the MC should accept managers' roles in Aruba-Admin-Role VSAs Which setting should you change to follow Aruba best security practices?
- A. Clear the MSCHAP check box
- B. Change the default role to "guest-provisioning"
- C. Disable local authentication
- D. Change the local user role to read-only
Answer: C
Explanation:
For following Aruba best security practices, the setting you should change is to disable local authentication.
When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.

NEW QUESTION # 50
Refer to the exhibit.
You are deploying a new ArubaOS Mobility Controller (MC), which is enforcing authentication to Aruba ClearPass Policy Manager (CPPM). The authentication is not working correctly, and you find the error shown In the exhibit in the CPPM Event Viewer.
What should you check?
- A. that the IP address that the MC is using to reach CPPM matches the one defined for the device on CPPM
- B. that the snared secret configured for the CPPM authentication server matches the one defined for the device on CPPM
- C. that the MC has valid admin credentials configured on it for logging into the CPPM
- D. that the MC has been added as a domain machine on the Active Directory domain with which CPPM is synchronized
Answer: A
Explanation:
Given the error message from the ClearPass Policy Manager (CPPM) Event Viewer, indicating a RADIUS authentication attempt from an unknown Network Access Device (NAD), you should check that the IP address the Mobility Controller (MC) is using to communicate with CPPM matches the IP address defined for the MC in the CPPM's device inventory. If there is a mismatch in IP addresses, CPPM will not recognize the MC as a known device and will not process the authentication request, leading to the error observed.
